Abstract

The invention is a cast-in-site concrete hollow slab, comprising reinforced concrete and form components, where the form components are wrapped in the reinforced concrete, and spacedly arranged, cast-in-site reinforced concrete ribs are arranged between them and each form component comprises top plate, peripheral side wall and infrabasal plate, which compose a closed cavity form component, at least one of the top plate, peripheral side wall and infrabasal plate is provided with reinforcing ribs and it is characterized in that the closed cavity of the form component is provided with at least a rod, at lest one end of the rod intersects and connects with at least a reinforcing rib. And the invention is applied to cast-in-site reinforced concrete or prestressed reinforced concrete hollow floor systems, house covers, walls, foundation slabs and hollow bridges.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, the cast-in-place concrete hollow slab is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom plate, the upper plate, the surrounding side walls and the lower bottom plate form a polyhedron cavity. Another example is that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor s...
